Based on the small amount of material we've seen, Odyssey would seem to take place, paradoxically, centuries before Origins' 1st-century BCE timeframe.
Of course, rumors have been circulating for a while about Odyssey's existence - however no actual gameplay has been leaked, unlike Origins prior to its announcement.
Ahead of E3, the setting of the next Assassin's Creed game appeared to leak. We can also look forward to learning about the big fall update Bungie has planned for Destiny 2 and finding out what game Remedy has been working on since shipping Quantum Break in 2016. That changed this year, with very little being said about the next game in the series. Here's when all the shows featuring PC games will be streaming live.
Hours later, Ubisoft confirmed it by posting a teaser of Assassin's Creed Odyssey on their Assassin's Creed Twitter page. The keyring in question seemed to confirm the Greek setting for the game, which had been part of rumours dating back to January.
While we don't know much more about the game at the moment, Kotaku reports that Odyssey will retain numerous RPG elements introduced in Origins as well as introduce a few new ones, such as dialogue options.
According to French site JeuxVideoLive, via Kotaku, the next installment in the series will be called Assassin's Creed Odyssey. The outlet has heard from sources that Origins protagonists Bayek and Aya will not be featured in Odyssey. While Origins altered the combat, Odyssey will introduce dialogue options, a first for the series.
It's the follow-up to Assassin's Creed Origins, which in itself was a soft reboot for the series after fans had grown exhausted of annual releases and repetitive mechanics.
